Title: PHP realizes the question answer saving and draft function in the knowledge Q&A website

Introduction:
With With the rapid development of the Internet, knowledge question and answer websites have become an important way for people to obtain information and solve problems. In order to provide a better user experience, Q&A websites usually provide functions for saving and drafting questions and answers. This article will use the PHP programming language to implement a simple knowledge question and answer website, and introduce how to implement the saving and drafting functions of question answers.

1. Basic page design of the Q&A website
First of all, we need to design the basic pages of the Q&A website, including the question list page, question details page, answer question page, etc. You can use HTML and CSS for page layout and styling. The following is a simple page design example:

<!-- 问题列表页 -->
<!DOCTYPE html>
<html>
<head>
    <title>问题列表</title>
    <style type="text/css">
        /* CSS 样式 */
    </style>
</head>
<body>
    <!-- 页面内容 -->
</body>
</html>

<!-- 问题详情页 -->
<!DOCTYPE html>
<html>
<head>
    <title>问题详情</title>
    <style type="text/css">
        /* CSS 样式 */
    </style>
</head>
<body>
    <!-- 页面内容 -->
</body>
</html>

<!-- 回答问题页 -->
<!DOCTYPE html>
<html>
<head>
    <title>回答问题</title>
    <style type="text/css">
        /* CSS 样式 */
    </style>
</head>
<body>
    <!-- 页面内容 -->
</body>
</html>

2. Saving and drafting function of question answers
In the Q&A website, users can choose to answer questions and save the answers or set them as drafts. The following is a sample code that uses PHP to implement the save and draft functions of question answers:

<?php
// 答案保存
function saveAnswer($questionId, $answerContent) {
    // 将答案保存到数据库中或其他存储介质
}

// 答案草稿保存
function saveAnswerDraft($questionId, $answerContent) {
    // 将答案草稿保存到数据库中或其他存储介质
}

// 获取问题详情及答案
function getQuestionDetails($questionId) {
    // 从数据库中或其他存储介质获取问题详情及答案
}

// 页面处理

// 提交答案
if ($_POST['submit_answer']) {
    $questionId = $_POST['question_id'];
    $answerContent = $_POST['answer_content'];
    saveAnswer($questionId, $answerContent);
    // 提交成功后的跳转或其他处理逻辑
}

// 保存草稿
if ($_POST['save_draft']) {
    $questionId = $_POST['question_id'];
    $answerContent = $_POST['answer_content'];
    saveAnswerDraft($questionId, $answerContent);
    // 保存成功后的跳转或其他处理逻辑
}

// 展示问题详情及答案
$questionId = $_GET['question_id'];
$questionDetails = getQuestionDetails($questionId);
// 对问题详情进行渲染展示，包括问题标题、问题描述等
// 对答案进行渲染展示，包括已保存的答案和草稿答案

In the above code, we use the saveAnswer function and the saveAnswerDraft function respectively Implemented the function of saving answers and drafts. The getQuestionDetails function is used to obtain question details and answers from a database or other storage media. Through form submission, we can submit the answers to the questions to the server for saving or setting them as drafts. When displaying question details and answers, we can display saved answers and draft answers as needed.

Conclusion:
Through the above sample code, we implemented a simple knowledge question and answer website, and successfully added the saving and drafting functions of question answers. Of course, an actual Q&A website may be more complex, with more features and details to consider. But hopefully this example can provide you with some inspiration and reference to help you build a more complete Q&A website.
